How to insert a string in another string in C -

i need insert string in string @ specific place. here's simple example:

char *a = "dany s."; char *b = "my name  *a , come ...  "; 

so, in string b in place of *a expect have dany s.

how ?

the best/easiest way use standard c conventions:

char *a = "dany s."; char *b = "my name %s, come from...";  char *c = malloc(strlen(a) + strlen(b));  sprintf( c, b, ); 

then c contains new string. when you're done c, need free memory:

free( c ); 

if want use c in output terminates line, can declare b as:

char *b = "my name %s, come from...\n";
